Visualization of tourism information using WordNet

In recent years, with the development of the Internet, and the rapidly increasing number of tourism portal sites and blogs, we can obtain a variety of tourist information on the Internet. If we have a specific need, we can obtain the required information through checking the retrieved results one by one. However, in order to see the whole trend of the results, it is necessary to analyze and visualize the document group. In this paper, by storing a set of tourism-related future words in WordNet, which is a concept thesaurus, we proposed a method using information from WordNet to visualize a document group as a conceptual graph. With the structure of a thesaurus, this method enables us to understand the contents of document group at a glance. Furthermore, by comparing the thesaurus structures, which are obtained from different background document groups, we can grasp the differences.
